Summary: We got this printer to cut down on the expense we were incurring with inkjet printers. By making it the default, and only switching to the inkjet when we NEEDED color, we have saved a fortune already. Also, this printer is fast and seems to be pretty reliable (we've had it 10 months with no hassles.) All of that would normally cause me to give it a five-star rating. However.... Trying to use the manual feed is a nightmare.
Summary: Comments about Brother HL-2040: This printer is fine for printing text on regular 20 lb paper, but don't expect too much more than that. If you need to print labels or envelopes,each one has to be hand fed into the manual feeder, which is flimsy and doesn't always guide the paper in straight. It will not print heavier weight papers very well...
Summary: The print quality is really nice (I have only used it to print text), but the pages curl no matter how thick or thin the paper. I've used cheap copy paper and expensive 30-pound resume paper, all with equal curling. It's kinda noisy when printing, quiets down right after it finishes, and then goes completely silent about 15 minutes after the last page is printed. I use mine for economical home printing since I print a lot.
Summary: I just upgraded from an HL-1440 which died a sudden death last night -- the sheet feeder broke. This one is a little noiser, seems a little flimsier, but boy is it a lot faster. For a $110 -- if I get one year out of it, I figure I'll be money ahead.
